Fig.1. Illustrates sandwich concrete.
In Situ concrete will be used on this project. Due to the Architectural design of producing exposed concrete on both internal and external faces, a sandwich panel will be used, containing a centred 50mm insulation tied in place using a non conductive thermal tie. The walls will provide an overall thickness of 300mm. The floors and ceilings will also be constructed using in situ concrete. Fig.2 determines that a 2 way flat plate of a thickness of 200mm will be sufficient for a 6m span. However, for the swimming pool area which spans 12m, we will require 500mm x 150mm post tensioned beams as determined in fig. 3. Beams are preffered over joists on this occasion due to the preferred Architectural design of the exposed soffit.
